List-I	List-II
(A) Chepil and Milne (1941)	(I) Protection of soil surface from wind action
(B) Surface creep	(II) Alternate arrangement of erosion susceptibility and erosion-resistant crops
(C) Vegetative residue	(III) Coarse soil particles
(D) Strip cropping	(IV) Mechanics of soil movement by wind

Choose the correct answer from the options given below:

Correct option is C

The correct answer is (C) (A)-(IV), (B)-(III), (C)-(I), (D)-(II)

Explanation:
• Chepil and Milne (1941): These scientists are renowned for their foundational research on the 'Mechanics of soil movement by wind'. W.S. Chepil is often considered the father of wind erosion science.
• Surface Creep: Refers to the rolling and sliding of coarse soil particles (0.5 mm to 2.0 mm) along the surface because they are too heavy to be lifted.
• Vegetative Residue: Crop residues left on the field provide physical protection to the soil surface, reducing wind velocity at the ground level and preventing particle detachment.
• Strip Cropping: An agronomic practice where erosion-susceptible crops (like maize) are grown in strips alternating with erosion-resistant crops (like legumes/grasses).

Information Booster:
• Wind strip cropping is usually practiced perpendicular to the prevailing wind direction to be effective.
• Chepil's work led to the development of the Wind Erosion Equation (WEQ), similar to the USLE for water erosion.

Additional Knowledge:
• Option (III) Coarse particles: Contrast this with Saltation (medium) and Suspension (fine).
• Option (II) Strip cropping: This is a highly effective 'bio-engineering' method for both wind and water erosion control.
